MEANS FOR OPERATING HYDROCARBON-BURNERS FOR METALLURGICAL FURNACES.

SPECIFICATION forming part of Letters Patent No. 757,606, dated April19, 1904.

Application filed March 5, 1903.

in means for operating hydrocarbon-burners for metallurgical furnaces.

Certain types of metallurgical furnaces are supplied with oil fuel atopposite ends through the medium of oil-burners. The oil fuel issupplied in this class of furnaces first at one end and then at theother. Heretofore it has usually been necessary for two operators tostand at opposite ends of the furnace, so that when the operator at oneend thrusts the burner at that end into the furnace the operator at theother end must withdraw the burner at said end. A third attendant hasbeen required to be stationed at another point, so as to start thefeeding of oil and air through the burner which is thrust inwardly andstop the feeding of the oil and air through the: burner which isadjusted outwardly. In case in the class of furnaces referred to onlyone attendant or operator is assigned for the work 5 of thrusting oneburner in and the other out it is necessary for him' to first adjust oneof the burners at one end and then walk to the 5 opposite end of thefurnace for the purpose;

of adjusting the burner at that end. When the course first mentioned ispursued, it is obvious that the services of three men are required,while if the second course is pursued much time is lost by the attendantin walking from one end of the furnace to the other.

The primary object of my invention is toprovide a construction wherebyone man at a given point can not only govern the adjusting inwardly ofthe burner at one end of the furnace and the adjusting outwardly of theburner at the opposite end of said furnace, or vice versa, but can alsoat the same time start the Serial No. 146,292. (No model flow of oil andair through the burner which is adjusted inwardly and stop the flow ofoil and air through the burner which is adjusted outwardly.

A further object contemplated by the in vention is the provision ofimproved means for adjusting the burners so as to direct the dischargeof oil and air'therefrom and onto the contents of the furnace at anydesired angle. 1

With the above and other incidental objects in View the inventionconsists of the devices and parts or their equivalents, as hereinafterset forth.

In the accompanying drawings, Figure 1 is" an elevation of ametallurgical furnace, showing my improved hydrocarbon bu'rners inconnection therewith. Fig. 2 is a view of the mechanism for operatingthe oil-burners and which is located in front of the furnace. Fig 3' isan enlarged detail View of one of the burners and means for supportingsaid burnerand permitting it to travel; and Fig. 4: is a detail viewlooking in front of the traveling roller, with the rails of the track insection.-

Referring to thedrawings, the numeral 5 indicates an ordinary form ofmetallurgical furnace. The openings forth'e int roduction of thehydrocarbon fuel are located, respectively, at opposite ends of thefurnace, as most clearly shown in Fig. 1. Extending from opposite endsof the furnace at an incli nation are parallel rails 6 6, forming atrack for the travel of a grooved roller or trolley '7. The inner endsof the rails of eachtrack are connected by a crossbar' 8, which crossbaris pivoted to a bracket 9, secured to the end of the furnace; The outerend of the track is suspended in any desirable manner, but is preferablyhung on arod 10, depending from a ceiling, beam, or rafter 11 ilrsuchmanner that the outer end of the track is raised, and hence -said trackis on a gradual decline from its outer end inwardly The rod ispreferably of two parts connected by a turn.- buckle 12, engaging rightand left hand threads on the respective. sections of the rod. By turningthis turnbuckle the-track may be erated by means of a suitable handle45. Extending from one end of the horizontal pipe 43 and leading to theleft-hand oil-burner is a pipe 46. Extending'from the opposite end ofsaid horizontal pipe 43 and leading to the right-hand oil-burner is apipe 47. The quantity of air flowing through the pipes 46 and i7 iscontrolled by means of valves 48 and 49, arranged in the respectivepipes. In the operation of this mechanism for supplying the burners withoil and air if, for instance, the burners are in the position shown inFig. I it is necessary under such adjustment of the burners to cut offthe supply of oil and air to the right-hand burner and causea flow ofoil and air through the left-hand burner. This is accomplished byturning the three-way valve in a direction to shut off the flow of oilthrough the pipe 38 and permitting said oil to flow through pipe 37, andconsequently through the left-hand oil-burner. At the same timethe'three-wtry valvecontrolling the airsupply is turned in a directionto permit the air to flow through pipe 46 and to shut off pipe 47. Ifnow the adjustment of the burners is reversedthat is to say, thelefthand burner is adjusted outwardly andthe right-hand burnerinwardlythe three-way valves of the respective oil and air supply pipesare turned in a direction to cut off pipe 3'7 and open up pipe 38, so asto allow the oil to flow to the. right-hand burner, and

to cut off air-pipe 46 and open up pipe 47, so as to permit the air toflow to said righthand burner.

From the foregoing description it will be.

seen that I provide a simple form of mechanism for obviatingdifiiculties which have heretofore existed in supplying themetallurgical furnaces with oil fuel and that by my improvements theoil-burners are readily regulated from one point and at the same timethe supply of oil and air to the burners is also regulated at saidpoint. I Furthermore, I provide a simple means for adjusting the burnerat any angle so as to direct the oil and airdischarged therefrom ontothe fire at the as particularly applicable to oil-burners and for use inconnection with metallurgical furnaces, yet I do notwish to beunderstood as limiting myself thereto, inasmuch as the invention may beapplicable to burners-for feeding any other kind of fuel and alsoadapted for use in other kinds of furnaces or heating devices. I also'donotwish to be understood as restricting myself to two burners lov catedadjacent to two openings of the furnace,
